Class
    Foam::functionEntries::elifEntry

Description
    Conditional parsing of and within dictionary entries.

    Part of the #if...#elif...#endif

    E.g.
    \verbatim
        Uinlet 15;

        #if (#calc "${Uinlet} < 10")
            ..
        #elif (#calc "${Uinlet} > 20")
            ..
        #endif

        pOutlet
            #if (#calc "${Uinlet} < 10") 0
            #elif (#calc "${Uinlet} > 20") 100
            #else 10
            #endif;
    \endverbatim

    The condition should return any boolean representation supported by
    \c Switch i.e 0, 1, true, false, on, off, yes, no.
